Question

Amobile home 36'x10' is to be located at an existing 100 amp/240 volt pedestal. What's the size of the sub feed to feed the trailer panel? The lighting and small utilization equipment lead is 3,750 VA heater is 900 VA at 240 volts, exhaust fan is 400 VA at 120 volts, range is 7,000 VA at 240 volts. Assume no manufacturer needments are available.

Answer 1

The size of the sub feed to feed the trailer panel should be able to handle at least 12,050 watts of power.

Step-by-step explanation:

To determine the size of the sub feed to feed the trailer panel, we need to calculate the total power consumption of the lighting, small utilization equipment, heater, exhaust fan, and range. From the given information, we have:

• Lighting and small utilization equipment: 3,750 VA
• Heater: 900 VA at 240 volts
• Exhaust fan: 400 VA at 120 volts
• Range: 7,000 VA at 240 volts

To calculate the total power consumption, we convert the volt-amperes (VA) to watts (W) and then sum them up. The sub feed size would need to be able to supply this total power consumption.

Let's calculate the power consumption:

1. Lighting and small utilization equipment: 3,750 VA → 3,750 W
2. Heater: 900 VA at 240 volts → 900 W
3. Exhaust fan: 400 VA at 120 volts → 400 W
4. Range: 7,000 VA at 240 volts → 7,000 W

Total Power Consumption: 3,750 W + 900 W + 400 W + 7,000 W = 12,050 W

Therefore, the size of the sub feed to feed the trailer panel should be able to handle at least 12,050 watts of power.
